Abstract
A method for controlling a three-phase brushless DC motor including a single hall sensor, the method including: A) measuring a deviation angle θ of a mounting position of the single hall sensor and storing; B) starting the motor: outputting six-path PWM signals by the microprocessor to control the operation of the inverter and allowing the single hall sensor to continuously and stably measure a position signal; C) obtaining a rotating angular velocity ω=360°/T in the last 360° electric angle cycle by the microprocessor; D) calculating a real-time position angle α=ωt+θ of a present 360° electric angle cycle by the microprocessor; and E) outputting the six-path PWM signals by the microprocessor to control the operation of the inverter so as to simultaneously energize the three-phase winding (U, V, and W); and switching a current direction of each winding.
